Junior Development Engineer

About OxSonics Limited

OxSonics was established in July 2013 to develop a new generation of ultrasound-based medical devices for drug delivery applications. OxSonics is currently conducting the first clinical trial of its platform technology to address a major unmet clinical need – metastatic liver cancer – and is in the process of developing the next generation of its technology towards further clinical indications.

OxSonics “SonoTran” platform has the proven capability to overcome the greatest challenge facing solid tumor cancer therapy by safely delivering drugs throughout tumors, including to those areas that lie farthest from blood vessels. SonoTran can be used to enhance delivery of any cancer drug. A major benefit of OxSonics’ technology is that it provides on-screen feedback to the clinician as to where drug delivery is taking place in real time. OxSonics is based in Oxford, UK.
